3M 7100264197 Quick-change Disc 3 in Ceramic Coarse Roloc Tr

Product Description

The 3M 7100264197 is a 3-inch diameter quick-change abrasive disc designed for use with Roloc TR Type R attachment systems. Built with a ceramic, non-woven construction, this disc delivers consistent coarse-grade material removal and surface conditioning on metal and other hard substrates. The non-woven structure allows the abrasive to cut aggressively while conforming to irregular surfaces, making it effective for deburring, blending, and finishing work. It is rated to a maximum of 20,000 RPM, supporting use with standard right-angle die grinders and inline grinders common in fabrication and maintenance environments. The brown disc color corresponds to the coarse grade within the PN-DR series.

This disc is suited for metal fabrication shops, maintenance and repair operations, and industrial finishing applications where rapid stock removal or surface prep is required. The Roloc TR attachment system allows fast disc changes without tools, reducing downtime during production or service work. It is commonly used on steel, stainless steel, aluminum, and weld seam cleanup tasks in both shop and field settings.
